I would like to have GTA 4 with ICEnhancer 2.1 or another enb+better texture pack(Lord's ones) + some vehicles+ Simple Native Trainer or Modding Pack by Hippiecommunist. With Ice+textures it isn't that bad, but all i can do is jerk it off on the graphics, I need some scripts like SNT.

Everytime I try to install all of them or just a vehicle pack I get texture pop-in, texture loading and fckn long loading time when i start the game. I've tried to install them one by one, with commandlines,change Nvidia control panel settings, but nothing works.

I have an I7 3770, 8GB RAM, ASUS GTX 770 2GB with not original Win8 and I bought it to play this game mostly, so it's fricking annoying. I use Gta 4 1.0.4.0 version.

So do you guys know any commandline that would work on my rig, or any solution? All i could figure out was scripthook makes it worse.

Next thing you should try is to install just one car, maybe the car pack is just too much. Or just get one of those lightweight car packs (with limited file size).

I personally don't have any cars installed because of the taxibug (and the performance issues that usually come with scripts that 'solve' this bug). But I guess it kinda depends on how much you're into cars, I personally don't mind the default ones
